If I install these into a thermal motion sensor (non-security-linked), will they last more than 9 months before I have to recharge them?

I would say it depends how often they are actively running. In my experience, using them in the same product as a disposable, I get 24 hours per charge or 3-4 times longer than that with a disposable. If you know how long a disposable lasts in your sensor, you could make a guess that this would last for your purposes.

Yo las uso en mi guitarra!, y me alcanza por un mes, antes de recargar nuevamente. Y no la uso a diario!.

Can't tell you. Recovering from hip surgery, upstairs, batteries are downstairs. I do know this is a bargain, batteries are fresh, and last a very long time in motion sensor lights. Hope this helps!

The batteries in the motion sensors and door senor gave me approximately 11 months. The motion and door sensors use different size batteries.

I have had mine for over a year now and they are still fine.A lithium-Ion battery shouldn't really go bad.Thay don't have a charge memory where they loose capacity every time you use them..Just don't leave them out in the cold and not charged because that does seem like it can mess them up and don't recharge until they have cooled off..

I used to work for a battery company. If you keep them charged you should get 3-5 years out of them. Store them in your basement or somewhere cool. Do not freeze them ever

I use these batteries in some burglar alarm sensors, and mark the date of installation. Most of the time (in at least half a dozen instances), I will get between 2 - 3.5 years of service on the Ultralife batteries. It's not 10 years, but it is far more than I would get from a standard alkaline.

I have used them about 5 hours a week and it has been 2 years and 9 months; they are still working. Just remember when installing them wear gloves.

They should last a long time as the unit is direct wired to 110 volts. So it's based on the shelf life of the battery. I have several direct wired smoke detectors and I only replace the batteries when one of them is low, then I replace all of them. batteries. I expect the batteries will last over 2 years.

Yes and No. These Tenergy Centura seem to hold a charge for along time, UNLESS the battery is in a warm/hot area (as in the attic for which I'd use a conventional battery). The problem is how is the battery connected to the smoke detector? If it's a push in and pull out its okay, if you have to clip on the connector you might break the terminal on the battery when you need to recharge it. I'd perform a monthly test on the smoke detector, but don't go past 12 months without recharging. I've found the MaximalPower needs to be rebranded as "MinimalPower" and totally worthless.

The ones I bought had exp. dates. I have been buying these for years, I use them in my wireless home security system and never had a problem.

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

Mine last at least 6 months, but a couple have lasted close to a year. It depends on the battery, weather, and how much traffic you have to trigger the alarm. The lithium 9 volt batteries do not work correctly because the voltage is too high and it causes lots of false alarms. Hope this helps.

We've had two LED motion sensor lights similar to this one outside for two years, operating on two D-cell batteries. We live in the far north with many below zero days, and they still work beautifully--with their original batteries!

The instructions say not to expose it to heat and/or UV sunlight for prolonged periods or it will degrade the sensor. They're best used as a temporary "band aid" solution on your jacket, or pack, or even in the car. Good to have a dozen around but won't take the place of a dosimeter. If stored in a cool dry place they are good for 10+yrs.

Yes, I'm using them in mine for about 3 months now. They seem to be holding a good charge. Time will tell if they continue to perform well.

They last very long, I bought this in July 2013, and I just recharged the D batteries at the beginning of December 2013. The batteries weren't even drained, I just wanted to make sure it wouldn't die before I went on vacation.

I've got this same set on my bike and I use rechargeable batteries in mine. They usually last about a month to a month 1/2 before having to be recharged. I've been using the same batteries since I got this set of lights about 4 years ago.
